iPad screen dims to very dark on login screen
Since taking delivery of 60 iPads for school I have noticed that when I fit the cases we bought the login screen fades to near black making it difficult to see the screen. On experimenting it seems that covering the two ambient sensor's (one in each of the top corners) causes this problem because on removal of the front cover the screen comes back. This did not happen before IOS15. Is this a software problem or a problem that the case designer was unaware of brought about by IOS15.
